Executive Summary

DEMOLITION PLAN 2
This paper provides a systematic approach to the identification of potential harmful
materials along with abatement procedures, loading of waste materials, sequenced demolition,
and disposal of all the waste materials associated with buildings in Eastwood Centre. The site is
to be converted into a mixed used development center comprising of commercial, retail and
residential components 1. This demolition plan will be used as the framework to ensure that
public health, the traffic, the environment and the neighboring structures are not affected by the
demolition activities.
The demolition plan has been developed after comprehensive analysis of the building's
specifications and all the demolition regulations. This detailed plan is designed to be approved
by the relevant authorities and satisfy the client before the actual demolition takes place at the
site.
Location
The building is bound by Rutledge Street, Trelawney Street and Rowe Street with
admittance to all facades. The pictures attached show the representation of the building to be
demolished from different viewing sides. The specific sites to be demolished are shown in the
plan drawing of the building below.
Height and Boundary
The buildings found around the site to be demolished have the heights ranging from 10-
15 m above the levels of the existing streets. There are also tall electrical distribution systems at

DEMOLITION PLAN 3
1 m from the building to be demolished. All around the building there are other buildings within
20 mm except on the sides adjacent to the streets.
Description of the Buildings to be demolished
The building to be demolished is generally constructed with load bearing masonry walls
except the existing concrete car park with different levels. The roofs of the building are either
timber framed steel framed or metal roofs. The building to be demolished is a one story structure.
The building is generally constructed on a concrete slab on the ground with still reinforcements
to provide more support. The building has fabricated glass windows and metallic and wooden
doors. The building consists of a series of bored rigid concrete piles. The building also comprises
of plasterboard, tile and terrazzo floors and glass skylights. Below is the plan of the building to
be demolished.
Protective Measures and Barriers
An A class hoarding should be constructed around the perimeter of the construction site
before the demolition process begins. In order to prevent the risk of falling objects a 8 class
hoarding should also be provided. The class B hoarding is to be established to the sides adjacent
to the street and foot paths. This would be on the western boundary and the Rutledge Street
frontage.
In addition to the A and B class hoarding, scaffolding should be erected in the frontages
where materials could fall from a height excess of 4 meters. In order to enclose debris and the
dust that comes from the site, the scaffolding should be clade with shade cloth and chain wire.

DEMOLITION PLAN 4
Dust control measures will be applied during the demolition to minimalize the dust from
spreading to the surrounding structures. A senior representative of the demolition contractor
should be at the site at all times to ensure that the safety guidelines and requirements are adhered
to.
It is not necessary to establish an exclusion zone since all the demolition debris is going
to be contained within the demolition boundary2. In the event an acceptable risk rises in the
process of demolition, the contractor will prepare a detailed Job Safety Analysis and Safety
Work Method Statement to inaugurate an exclusion zone.
All the traffic will be held within the boundary during the demolition process. The site
will always be closed to pedestrian traffic and security personnel should be deployed to man the
pedestrian traffic in and out of the demolition site.
Equipment required
The following equipment will be required for demolition of this building.
-1- Caterpillar 350 High Reach Excavator with pulverizer and shear attachments
-1- Caterpillar 325 with shear, hammer and grapple attachment
-1- Komatsu PC300 Excavator with grapple and sheer attachment

multi-year models. (ISPRS International Journal of Gea-Information, 2015) 312.

DEMOLITION PLAN 6
assembling to ensure that they are functioning in accordance with the design and ensure that all
safety mechanisms have been installed. The contractor should ensure that the equipment is
operated by experienced, competent and properly trained employees.
Site Mobilization
After pre-mobilization planning and submission of all the requirements has been done, a
pre-demolition inspection should be done and a documentation of the existing site condition be
prepared before any on-site work commences. Site mobilization will then follow after the pre-
demolition inspection to understand the current configuration of the site such as the security
requirements, site hazards and the residual liquids. The job site turnover requires adequate
personnel and time.
The demolition contractor will use the following personnel in the demolition process
Project Oversight: - operations superintendent - Mr. James Smith
- Site safety and health manager (SSHO) – Mr. John Kennedy
Decontamination and demolition (D & D) team: - 2 labor foremen
- 6 laborers
- 5 operators
Hazard mitigation team: - 1 supervisor
- 9 laborers

DEMOLITION PLAN 7
All the personnel should ensure they wear protective gear in accordance with the rules and
regulations. They should also familiarize with the site and have information of the immediate
environment surrounding the site. The hazard mitigation team should be made up of experienced
and skilled technicians with a minimum of 10 years in the construction industry. The overall
demolition work will be accomplished by the decontamination and demolition team and the
hazard mitigation team in a safe and systematic progression with the close coordination of the
project oversight team. The SSHO will ensure that there is a "zero tolerance" safety culture and
ensure that he assess the potential hazard for every procedure at the site.
PRE-DEMOLITION ACTIVITIES
1. Utility Abandonment
Geophysical survey will be performed by the demolition contractor to locate all the utility
lines within the site perimeter and ensure that all the utilities to the building have been
terminated. The site conditions will dictate how the isolation of the building from the utilities
will be performed. The Dig Safe of New York should be utilized before the actual demolition
observation requests. All the identified utilities should be marked clearly with markings that will
remain visible during demolition. Underground utilities (such as sewer, gas, water, electric, or
telephone) that have been identified but not terminated should be drawn in a drawing that is to be
presented to the site oversight team.
2. Building Structural Integrity Evaluation
A professional engineer should be contacted by the contractor to evaluate the structural
integrity of the building. The evaluation should include details of the building's current
condition and a recommended approach for building demolition. The evaluation should also

DEMOLITION PLAN 8
indicate the various measures to be undertaken to prevent the unplanned collapse of the building.
The engineer will perform the assessment in accordance with
SEI/ASCE 11-99 Guidelines for Structural Assessment of Existing Buildings
29 CFR 1926.850 – Safety and Health Regulations for Construction, Preparatory Operations
ANSI AI – 6 – Safety Requirements for Demolition Operations
3. Hazard Material Characterization
Radiological surveys, analysis, sampling and historical knowledge will be used as
outlined in the Sampling and Analysis plan to pinpoint hazardous and radiological materials that
may be encountered during the demolition process. The hazardous materials should be identified
and quantified. These materials include lead, fluorescent light fixtures, thermostats, light ballasts,
mercury/sodium vapor, ACM and capacitors4. Once the wastes and the hazardous materials have
been identified they should be removed or stabilized and they should be packaged separately
from other building debris.
The proper disposal requirements will then be identified using the process knowledge and
analysis of the samples. The materials will be transported away from the building to disposal site
prior to the demolition of the building. The disposal and the transportation of these materials
should be done in accordance with the local regulations and guidelines.
4. Pre-demolition ACM Survey

Merrifield james, Demolition Plan (CutBank, 2017) 210

DEMOLITION PLAN 9
A licensed asbestos inspector will perform a pre-demolition asbestos survey in both the
exterior and interior of the building with the roof included. The goal of the survey is to correlate,
evaluate and quantify all the materials containing asbestos. The survey will then provide the
guidance for the removal of these materials prior to the actual demolition. Any material with a
layer that contains greater than 1% asbestos will be considered as asbestos-containing material
(ACM).
DEMOLITION ACTIVITIES
After all the pre-demolition activities have been performed, the contractor will then go ahead
with the demolition of the building.
1. Dust Control Methods
Dust control mechanisms will be established during the actual demolition of the building
to prevent the spread of contamination and also maintain the particulate level at the permissible
exposure level (PEL) as specified in 29 CFR 1926. 555. The dust control measure should consist
of dust suppression measures as well as ambient air monitoring to substantiate the realization of
dust suppression. Below is a summary of the dust control to be implemented during the
demolition.
Applying a water spray during wreckages/ waste handling and to unpaved vehicle access routes
at the site as required.
Wetting demolition equipment and active demolition area as required.
Keeping the speed of vehicles below 10 miles per hour on unpaved surfaces
Covering debris/ waste piles

DEMOLITION PLAN 10
Hauling wastes /debris leaving the site in closed or covered containers
A spray pump and nozzle system should be applied in suppressing fugitive dust in the
attempt to prevent overly wet conditions, conserve water and avoid runoff and ponding. The
water used for dust suppression will be obtained from the on-site water source. Demolition
activities with the potential of causing dust such as transportation of debris, building demolition,
and piles of debris and loading of waste should be closely monitored for radioactivity and dust
particulate in accordance with the procedures described.
2. Building Demolition
The demolition of the building structure will start by removing the low rise portion of the
structure attached to the main high rise section. Cat 345 with a shear attachment will be used to
perform the removal procedure. Where possible, the low rise additions will be removed and size
reduced from within the structure's footprint. The demolition the will proceed from the top to the
bottom bay by bay through the building. The cat 345 operators will shear the roof trusses
attached to the building with the close supervision of onsite superintendent and Mr John
Kennedy. The roof truss on the opposite end along the perimeter of the building will then be
sheared and the removed beam to be lowered. All the roofing should be dropped alongside the
truss segments. The trusses and the debris that has been generated will be allowed to accumulate
on the slab of the building. All the horizontal beams of the building will then be removed by
shear as well as all the vertical columns which should be sheared at the bottom. Approved torch
cutting procedures will be used to remove bolts used to attach the structural steel columns to the
concrete slab prior to the demolition. Controlled free fall of the intermediate platforms suspended
from the structure's main framework will occur as the demolition progresses

DEMOLITION PLAN 11
High sections of the building will be demolished using cat 350 UHD track hole attached
with a shearer. The high reach operator will be in charge of the safe dismantlement of the upper
section of the building. The first roof beam will be cut at the end just inside the column line then
the beam will be bent before being freed on the opposite side. The beam will be lowered and
undergo size reduction. The generated debris will be allowed to collect on the flow below and
the process will be performed on the lower floor too. Below is a graphical illustration of the
demolition.
Clean Up and Site Restoration

DEMOLITION PLAN 12
All the debris generated will be removed from the demolition site. The waste will be
transported to the appropriate landfill or recycling of steel. After removing all the waste, all the
temporary facilities will also be dismantled and disposed of properly. A post-construction
radiological survey of the surface slab and the surrounding area will be performed. Site
restoration will then follow through restoring disturbed areas to the pre-demolition condition.
